JOHNQG. GnoN-BE'BG; both citizens of the I United, States of America, residing at Grand Rpidsgfinthe.county of Kent and State of Michigan, have invented certain new 'and useful Improvements in FirelessjBakers; and

weide herebydeclare'thefollowing to be a full, clear,1andexactdescription ofthe invention, suoli as will enable others skilled in the arttovwhieh it appertains to make and usethcsa-me.

Our invention relates to improvements in iieless bakers, and its object is to provide the saine withv various :newnnd usefull features, wherebya ghi temperature and(- dry heat ma be proper y and economically applied to suc articles, and, to prdvide the device with various-anew.- anduseful features, as hereinafter more fully described and particularlyf pointedout 4inthe claims. f Our-device consistsvessentially of a case or receptacle provided with a lining, which is a non-conductorgotheat and'iire-proof, one or more solid bodies adapted to absorb and give off heat, a suitableiack or support for the same, together witli the; vessel in. which the article to be .baked maybe supported and conveniently placed in or removed from the case, and. in various details of construction 1- and arrangement, 'as vwill moie'full appear by reference t0- the accompanying rawmgs,

Figure 1.is a perspeetivejview of the device elosed;-Fig. -2.ia transverse section of the same on the line 2-2 of Figs. 1. and 3 5 Fig. 3. a plan view of the saine with the cover opened up and the removable non-conducting pad omitted; and, Fig. 4. a perspective of the rack.

When vclosed this oase, together with the lining, forms a receptirrn'ntaess BAKER. l

tacle adapted `to recivara'clcshoivn-in per: Vspectiw` in Fig. 4. together .with its contents;

said rack preferably-consisting of a .tray .5 ofsheet metal adapted toreceive anyfdripor overiiowfrom the cookingvessel and also to receive `and support a` block 10 vof heatA ab'- sorbing material preferably ofsteatite, loommonly knoivn as soapstone, 'upon Which'block -is placed any convenient vessel 12 tocontain or support the material to be baked. Rods BEST AVAILABLE COPY bent twice at right angles form vertical supports 6 near the respective corners of the tray and are attached thereto at their lower ends, th middle'horizontal portions of said rods ol'ming` handles 7 15o-'manually lift and move the rack and its contents. Vertically adjust# able on these rods areftransverse su ports 8 adjustably held by set screws'Q. v(lb these supports may also be placed an upper block 'of steatite 11, adjusted at proper `distance from the material to be baked -to aced iii some suitable receptacle 12 and receives a preliminary heating 1n any suitable oven.

properly Y At the same time the blocks of steatite 1() and 11 are also heated in any convenient manner.v These blocks together with the vessel containing the materialD to be baked are then arranged upon the rack, and the Whole lifted by means of the handles and placed within the oase, the u per removable pad of non-conducting and 'e-proof materialplaced above' the rack and the 4case closed. The blocks of steatite will ive off suflicient heat to properly maintain t e tem perature of riw interior of the device and the material will in a short time be fully baked without further attention.

What We claim is: 1. In a tireless baker, the combinatiorvof a case, a heat insulating lining and a fire-prooflining inthe case, a removable rack in the: l ense, and one or more -heatmgbodies one of which adj ustably supported bythe rack. 2. In a tireless baker, the combination of a case, a heat insulating and fire-proof linin in y the case, heating blocks, .md a Vrenova le rack in the case, said rack having spaced part and super-posed su lports for the lating and fire-proof lining in the case, a tray, vertical rods attached to "the tray near its ocks the upper, support ing vertically, adjustable.
